Agreed. It's real nice feeling when you can look at your desktop and say "Wow! I made this!". That is assuming that you actually like the stuff that you make though. Read some tutorials and that won't be a problem.
I made this thing in 3D Studio Max 7 in 6 minutes. It's all in the reflections. They're just simple boxes and circles.
I just started an adobe photoshop contest for people making wallpapers, I also entered one. Go to my site and check out the forum, then go to "Adobe Photoshop Image Arena" and look at this months contest.
